IMPROVEMENT IN SHUT-MILLS .AND SEPARATOS.

To all whom it may conce/ru:

Be it known that we, J oNATHANMILLs and ALBERT G. WALDO, ofthe city and county of Milwaukee, and State of vVisconsin, have invented a new and useful improvement in Sinut-Mills and Separators; and We do hereby declare that the following is a` full, clear, and exact description thereof, which will enable those skilled in `the art to make and use the same, reference beingvhad to the accompanyiugvdrawing forming part of this specification, in whioh Figure l is a perspective view of our invention, and

Figure 2, a longitudinal sectional view.

Similarletters of reference, in each of the figures, indicate'correspondin g parts.;

The nature of bur invention is to produce a combined smut-machiue and separator whichwill thoroughlyclean grain ready for grinding.

A, the frame-work.'

B, the box in whichare thegrain-scourers.

C, the upper scourer, fastened permanently.

D, the lower scourer, which revolves: These scourers are made of burr-stone, vuloanite, emery, or any E, a fan fastened tothe same shaft with the lower scourer, and revolves with it.

F, scourer-shaft.

G, pulley on shaft F.

H, pulley on shaft I.

I, upright shaft.

K, bevel cog-wheel on upright shaft I.

L, COg-Wheel-meshing into wheel K.

M, main driving-shaft.

N N', fans on shaft M.

O, sieves. Y

I, lole for cockie to come out.

Q, air-conveyer.

R, divisionin air-conveyer Q.

S, air-conveyer.

T, pulley on main shaft.

U, hopper for the grain.

V, opening for the' grain to pass to thescourers.

W, eccentrics which shake the sieves.

X, hanging hooks which hold the sieves.

Y, covers to the fans N N'.

Z, belt whichdrives the scourer D.

scourers.

" Operation.

Let the grain fall into hopper U,from which it will fall onto sieves O, and, as the main shaft revolves, ec'

centrios W shake the sieves, and the grain falls through the sieves O, the chaff and oats falling over the sides; and, when the grainfalls on the lower-sieve O, the cockle and small seeds go through that sieve, l and fall out of hole P. The grain falls out of hole c into the opening V, and thus to the scourers. What-A ever chaff, dust, or cockie goes out with -the grain is sucked up through spout Q by means of ,fau N, the

dust passing out-through Va hole inthespout up bythe fan, and the cockle falling down over the division 'R iu the spout Q, and out through spout a, and, as

the scourer D revolves, the grain is scoured, and the fau E blows the grain and dust out. through opening b. The dust is drawn up through spout S by the draughtcaused by fau N. The main shaft M, put in motion by a belt over pulley T, and bevel-wheel L meshing intojwhe'el K, revolves shaftI and pulley H, and belt Z revolves the scourer E.

We do not claim as new the several devices above described,'nor any general combination of the same.; but

What We'claim, and desire to secure by Letters Patent of the United States, 'is- The improved arrangement of parts in the smutmill and separator herein shown, consisting of the box B, smooth burr or emery scourers C and D, fans E, and shaft F, with air-conveyer Q, partition R, sieves 0, operated by eccentries W Won shaft M, with fans N N and air-conveyerA S, when said parts are construoted, arranged, and operated as'shown :and for the purpose-set forth.
